' IMPROVEMENT IN SUGAR-CANE lVllLLS.

Specification forming part of Letters Patent No. 23,128, dated March 1,1859.

To all whom it may concern:

Be it known that I, A. VAN TRUMP, of Lancaster, in the county ofFairfield and State of Ohio, have invented a new and useful Improvementin Sugar-Cane Mills; and I do hereby declare that the following is afull, clear, and exact description of the same, reference being had tothe accompanying drawings, forming a part of this specification, inwhich- Figure 1 is an end View of a cane-mill with my improvementsapplied to it, and Fig. 2 is a vertical longitudinal section of thesame.

Similar letters of reference in each of the several figures indicatecorresponding parts.

The nature of my invention consists in the combination, in a sugar-canemill, of two or more intermediate small feedrollers with four or morelarge crushing-rollers, said small feed rollers being arranged betweenthe large crushing-rollers at such a point that their peripheries workin concert 011 the same line as do the peripheries of the largecrushing-rollers, and thus form a support and act as a feedmotion, atthe center of the machine, to the ends of the cane-stalks as soon asthey emerge from between the first pair of crushing-rollers, and untilthey pass in betweenthe second pair of crushing-rollers. By this featureof my invention the fatal defect in caneerushing machines which employfour or more roll ers is overcome, said defect being the verticalpassage of the ends of the stalks as soon as they escape through thefirst pair of rollers down between the lower rollers of the first andsecond pair, and a consequent chokage and stoppage, and very oftenbreakage, of the machine. The great benefit of my improvement can hardlybe summed up in words, when the serious obstacles which the above defectpresents to the perfect crushing of sugar-cane by rollers not having mysimple but effective improvement combined with them are taken intoconsideration.

My invention consists, second, in the par.- ticular arrangement,hereinafter specified, of the sustaining-frame, crushing and feedrollers, and gearing, whereby great strength and steadiness in theparts, perfection in the operation, and facility of adjustment areobtained.

To enable others skilled in the art to make and use my invention, I willproceed to describe its construction and operation.

A represents the frame of the press. This frame consists of two strongside plates, a a,

with horizontal flanges 'b b, a base-plate,- b,.

Each of the rollers has its bearing in boxes gg, fitted in the sideplates, 1) b, as shown. The bearingboxes of the lower roller of each setare made to rest on wedges h h h h so that by pulling out the wedges hif and driving in h it? these rollers can be raised and brought nearerto the upper rollers. The effect will be just the reverse by pulling outthe wedges h h and driving in h h".

C O are the small intermediate feed and supporting rollers. They arearranged so as to close up the vertical space between the two sets ofrollers, and so that their peripheries work in concert or operate uponthe canestalk .in the same line as do the peripheries of the largecrushing-rollers, and thus insure a straight and certain passage of thestalks through the machine. These rollers act as supports, guides, andcrushers, and also as a feed-motion. The large crushing-rollers havespur-wheels D D D D 011 the ends of their shafts, and the two sets arecombined by the spur-wheel E, as shown in Fig. 1. On the opposite endsof the lower one of the first or preparatory set of crushing-rollers alarge spur-wheel, F, is arranged. This roller gears into a pinion, G, ofthe lower one of the intermediate set of feed-rollers. H is adrivingpulley or spur-wheel on the shaft of the lower roller of thepreparatory set of crushing-rollers. By this arrangement of gearingit-will be evident that if the power is applied to the pulley H all therollers will be set in motion, and that the cane-stalk will be passedhorizontally through or between the three sets of rollers.

It should be remarked that the effect of the small rollers upon thestalks is made equal to that of the large'rollers, by reason of theirThe abovespecification of my improvement speed being much quicker thanthe speed of in sugar-cane mills signed by me this 8th day said rollers.of February, 1859.

What I claim as my invention, and desire y to secure by Letters Patent,is A. VAN TRUMP. 7 The combination, in a sugar-cane mill, of two or moreintermediate small feed-rollers, Witnesses:
